BOLT AND NUT GUTTER.

Appiication mea october so, 191s. serial No. 260,246.

To all whom it may concern f Be it known that I, WILLIAM B; CAnoLUs, acitizen of the United States, residing at Sterling, in the county ofWhiteside and StateA of Illinois, have inventedl a new and usefulImprovement in Bolt and Nut Qutters,of which the following is aspecificatlon. This invention relates particularly to bolt clippers, orcombination bolt clippers and nut splitters.

Theprimary provide an improved implement of the character described,having improved adjusting means to insure proper closing of the blades.Further objects are to provide a simple, staunch and durableconstruction having improved to provide improved hand-levers, of slmpleand cheap construction'.

The invention is illustrated, in its preferred embodiment, in theaccompanying drawing, in which- Figure l represents a broken plan viewof the improved device; Fig. 2, a side elevational view of the same;Fig. 3, an enlarged y isectional view, taken as indicated at linev 3 ofFig. 1; Fig. 4, a perspective view of one of the adjusting devicesemployed in connection with a hand-lever fulcrum of the device; Fig. 5,a perspective view, showing a guide bolt which moves in longitudinalslots in vthe plates, constituting the frame of the head of theimplement and which serves also as an interlocking connection between apair of'adjusting screws of the form shown'in Fig. 4; and Fig. 6, aperspective view of one of the adjustable lever-fulcrums.

In the preferred embodiment, which is illustrated, A, A represent a pairof swing ing blades, joined by pivots 1 to connecting plates 2,constituting a frame for the head of the implement; B, B, a pair ofhand.-

levers having their short arms connected by pivots 3 to the long arms ofthe blades A;

and C, C, a pair of adjustable fulcrums for the hand-levers B, each ofthe fulcrums C having an adjusting device C1 capable of movinglongitudinally in guide slots with which the plates 2 are provided.

In the illustration given, the blades A are provided with longitudinalcutting edges 4 and with blade portions 4a affording cutting edges 4bwhich are perpendicular to the cutting edges 4. The blades may be usedfor clipping bolts, or for splitting nuts, as desired.

Specification of Letters Patent.

object of the invention is to means for adjusting the blades, and jPatented Mar. 4, 14919.

which serve to house the'inner ends of the* hand-levers and connectingparts. The offset portions 2 of the plates are provided withlongitudinal guide slots 5 in which are received the head-'portions offulcrum-adjusting stems of' the character shown in Fig. 4.

Each of the hand-levers B, preferably comprises a wooden handle 6 and apair of heavy metal plates, or stampings, 6a. The plates 6a are providedwith complemental. semi-tubular shank portions 6b adapted toy receive'the handle 6, and are provided further with flat portions 6 whichafford between them a laterally open slot 6d. The ex tremities of theflat portions 6 embrace the rear ends of the long arms of the blades andare connected therewith by means of the pins 3, the ends of which pinsare housed by the offset portions 2a of the plates 2.` Theconcavo-convex shank` portions '6b ofy the;

handle-attaching plate 6a are connected with the wooden handle 6 bymeans of rivets 7.

vIt is preferred to equip one of the handlevers with' a rubber buffer 8,which-is at-4 tached by means of a pin which is capable of slidingfreely through'a perforation in Vthe hand-lever. Thisvis not essential,however. Y

Each of the fulcrums C, inthe illustration given, comprises a shortheavy pin which is provided with a transverse threaded perguide slots 5of the plates 2. It will be un-` derstood that the head portions l1a ofthe twov adjusting screws abut against each other and occupy the guideslots 5. Theaadjacent surfaces of the head portions l'gare other in themanner shown in Fig. 4. The

.110 provided with recesses 1l" which'l 'cross'feaclw"l iofset portions2 of plates 2, the washers adjusted posit-ion.

.15 that inasmuch'as the heads of the adjusting 1 embracing the outersurfaces of the plates, as will be understood. The bolt 12 serves as aguide bolt and connection between the rear portions of the plates 2 andalso 4as a means for locking the adjusting screws in l It will beunderstood -screws are confined in the slots 5, turning the adjustingscrews in the threaded sockets 10 of the fulcrum C will adjust the fullcrums toward or away from the longitunecting proved character and' of 1struction.

4 EitherI one of dinal center line of the implement, thus enabling theblades A to be adjusted so that the cutting edges will meet properly.the recesses 1l", may serve to receive the connecting bolt 12, depending-upon the recesses which is most available when thefulcrum is adjustedto the desired position. Y

The adjusting devices here illustrated and described render unnecessarythe use of eX- .terior adjusting devices, such as are commonly employedfor connecting the handle portions of bolt 'clippers to the base orconortions which are pivotally -con- 'nected with the blades. Moreover,this adjustment is independent of the use of any buffer or stop betweenthe hand-levers.

The hand-levers described are of the imcheapened con- The hand-leversmay be made adequately strong at a very low manufacturingI cost. Thesaving in the use of metal 1s material, and the construction providesfor the use of wooden handles. This is especially desirable where thedevice may be used for cutting electrically charged wires,

l since the wooden handles themselves afford ya fair degree ofinsulation, and the insulatlbe crums for ing effect may be increased, ifdesired, by wrapping or jacketing the handles with additional.insulating material.

The foregoing detailed description has been given for clearness ofunderstanding only, and no unnecessary limitations should claims shouldbe construed as broadly as permissible, in view of the prior art.,
